我添加到我的环境变量中
SELENIUM_SERVER_JAR = C:\selenium_drivers\selenium-server-standalone.jar
我在这里下载的http://selenium-release.storage.googleapis.com/index.html?path=2.46/
Python 脚本:
from selenium import webdriver
webdriver.Opera()
输出:

我期望 jar 定义了所有内容，为什么我找不到驱动程序类？
最佳答案
根据您的问题，您似乎在使用适用于 Opera 12 及更早版本的旧驱动程序。假设您正在尝试使用最新版本的 Opera，您将需要使用以下站点提供的驱动程序:OperaChromiumDriver
该站点列出了示例 python 代码，我已确认这些代码可以在我的机器上运行以打开和驱动 Opera:Python Examples for OperaChromiumDriver
import time
from selenium import webdriver
from selenium.webdriver.chrome import service
webdriver_service = service.Service('C:\\Users\\Kris\\Downloads\\WinPython-32bit-2.7.9.2\\operadriver.exe')
webdriver_service.start()
driver = webdriver.Remote(webdriver_service.service_url, webdriver.DesiredCapabilities.OPERA)
driver.get('https://www.google.com/')
input_txt = driver.find_element_by_name('q')
input_txt.send_keys('operadriver\n')
time.sleep(5) #see the result
driver.quit()
编辑: 查看 selenium 的更改日志，看起来对基于 Presto 的 Operas 的支持在 2.45 之后停止，这就是您收到错误消息的原因:CHANGELOG
关于python - 用 selenium python 驱动 Opera，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31055124/
